Answer:
Density of Sand is .
Explanation:
Given Empty Density bottle weighs 23.5gm(W=23.5gm)
Weight of bottle when completely filled water=48.4gm
So amount of water required to fill the bottle=Weight of bottle filled with water-W
Amount of water required to fill the bottle()=48.4gm-23.5gm
g
Since we know density of water and
We can calculate volume of empty space in the bottle(V).
V
V=
V=
V=24.9
Now bottle is partially filled with sand,and weight of bottle is ()36.5gm
So,
Amount of sand added ()=36.5-Weight of the bottle
=13g
After filling the bottle with water again,the weight of the bottle becomes (=56.5g)
Therefore,
amount of water added to the bottle of sand in grams = -36.5gm
amount of water added =56.5g-36.5g
amount of water added =20g
As the density of water = 1g/
Amount of water (in grams )=Volume of water occupied
20=volume of water added
Therfore volume of water added to the sand filled bottle()=20
As we know the total volume of the water bottle(V),
Volume of the sand occupied in the water bottle=V-
=24.9g-20g
=4.9g
We know,
Density=Mass/Volume
Therefore,
density of sand =
density of sand =
density of sand =
